Toshiba puts next-gen NAND flash memory in production

Toshiba America Electronic Components announced it has developed second-generation 19-nm process technology that it will apply to mass production of 2-bit-per-cell 64-Gbit NAND memory chips later this month. Toshiba has used the new-generation technology to develop 64-Gbit NAND memory chips with an area of only 94 mm2. This next generation can achieve a write speeds of up to 25 Mbytes/s – the world's fastest class in 2-bit-per-cell chips.
Toshiba is also developing 3-bit-per-cell chips by using this process technology and aims to start mass production later this year. The company will initially introduce 3-bit, multilevel-cell products for smartphones and tablets by developing a controller compatible with eMMC, and will subsequently extend application to notebook PCs by developing a controller compliant with solid-state drives.
